phPOP3clean is a spam, virus, and worm filtering system for POP3 email accounts.

POP 3 client is a PHP class that allows you to access mail boxes using the POP3 protocol. It provides a stream wrapper class for retrieving messages like files using the PHP fopen function, establishes secure connections using TLS, accesses servers using normal and APOP login methods, supports authentication mechanisms such as PLAIN, LOGIN, CRAM-MD5, NTLM (Windows or Linux/Unix via Samba) via the PHP SASL library, and supports listing of message sizes, retrieval of a message at once, separating the headers from the body, retrieving a message in small chunks to not exceed the available memory, and deleting messages.
Net_NNTP is a PHP/PEAR library for communication with NNTP servers. Net_NNTP handles connection and protocol-level commands (RFC977), including many non-standard commands (RFC2980), via a user-friendly API which hides the actual NNTP commands/syntax. Some knowledge about NNTP and general knowledge about email and MIME is required, since parsing of content and headers is left up to the user. Net_NNTP allows advanced users direct usage of NNTP commands via the separate protocol implementation. Net_NNTP includes a fully-functional NNTP to HTML gateway demo application.
